By keeping and dropping the price of the iPad mini retina $100, Apple has sunk the used iPad mini market. In February of 2014, I was able to sell a 15-month old iPad mini for $250; which with a retail purchase of $330 worked out to a monthly cost of $5.33. If today, I were to sell my Retina mini - which I bought on sale last February for $350 - I would be lucky to get $230 ($20 less than a refurbished Retina mini) for a monthly cost of $15 ($120/8 months). It would be even worse if I had paid full retail of $400, the cost per month would be $21.25 a month. True, the longer you hold on to the product, the better the amortization, but with three minis for sale plus refurbs, Apple has cornered the mini market. If you want to upgrade now, you are going to take a bath. It's a buyer's market.
